Description

• Application: Optimization of enantioselective high-performance liquid chromatography-tandem mass spectrometry method for the quantitative determination of 3,4-methylenedioxy-methamphetamine (MDMA) and its phase-1 metabolites in human biological fluids.: This study highlights the use of hydrochloric acid solution in the sample preparation process for precise analytical determination of MDMA and its metabolites using HPLC-MS/MS (Sprega et al., 2024). Coprecipitation as a One-Step Se Separation for Determination of Isotope Ratios Completed with Revised Uncertainty Evaluation.: This research employs hydrochloric acid solution in the coprecipitation method for selenium isotope separation, enhancing analytical accuracy and reliability (Karasiński et al., 2024). Removal of Methyl Red from Aqueous Solution Using Biochar Derived from Fennel Seeds.: This paper explores the use of hydrochloric acid solution in the preparation of biochar for effective removal of methyl red dye from water, contributing to environmental cleanup efforts (Paluch et al., 2023). Tyrosine Amino Acid as a Foulant for the Heterogeneous Anion Exchange Membrane.: The research investigates the use of hydrochloric acid solution in the study of tyrosine amino acid fouling on anion exchange membranes, providing insights into membrane fouling mechanisms (Kharina and Eliseeva, 2023).
